Police say Dennard was pulled over around 2 a.m. and cited with suspicion of DUI, refusing a chemical test, and a driving infraction, according to the report.
Dennard was placed on two years probation in March after being convicted for felony assault on a police officer in an April 2012 incident, prior to being drafted by the Patriots. He will also serve a 30-day jail sentence beginning Mach 1, 2014 for that conviction.
It's unclear how Thursday's arrest will affect Dennard's probation status or his delayed jail sentence.
The arrest comes as former teammate Aaron Hernandez faces a murder charge and less than a week after owner Robert Kraft said the team would take a hard look at its vetting process going forward.
Hernandez was released by the Patriots less than two hours after his arrest.
